This is just an arbitrary question, but why don’t long literals support lower case

l

? because it looks like floats do with

f

.

this was done on purpose, because in some alphabets

l

looks like

1

. Yup, it's arguably wrong to use such alphabets for writing code, but here we are. Also many coding best practice guides and conventions demand use of upper case

L

in such circumstances, so Kotlin team decided to make it explicit.

thanks for the explanation 👍 i learned something today 😄

Ah I see. Thanks for that 😄
